Archiving Emails in CRM

Hi Experts,

I am trying to archive E-mails recieved in the CRM system.

To do so, I am trying to schedule a SARA job to archive WORKITEMS in the system.

But when I try to execute the report WORKITEM_WRI in test mode and enter the parameters, I get the following error:

"No work items for archiving exist for your selection".

Is it the correct way to archive e-mails? Else, what is the exact procedure to be followed for the same.

Any help on the same would be highly appreciated.

Regards,

Saumya
